GPCorrelation : Différence entre versions

How to call it

For using the GPCorrelation class, the developer has only to create such an object as is:

gpCor = new GPCorrelation();

or:

gpCor = new GPCorrelation("widgetId", "MyMatrix");

Display

We will get:

By selecting the type of parameters, we may enter data for correlation/covariance matrix for Keplerian/Cartesian/LOF cartesians parameters. The different displays will be:

• In case of Keplerian parameters:

• In case of cartesian parameters:

• In case of LOF parameters:

So we may have a covariance matrix rather than a correlation one:

If the initial correlation (resp. covariance) matrix is not null, a specific pop-up window will appear to ask for the type of conversion. A bit as for the GPOrbit widget, it will be possible to do this conversion between correlation and covariance matrices (but not between the different type of parameters) using a kind of “pivot” notion.

How to use it

Therei no exactly corresponding correlation/covariance matrices inside PATRIUS but GENOPUS gives some utility classes and methods to use them.
